BOULDER, Colo.—A woman has escaped serious injury and has refused medical treatment after a cow knocked the woman down and walked on her legs in Boulder.

Boulder Open Space and Mountain Parks ranger Pete Taylor says the woman was riding her bicycle along the South Boulder Creek Trail on Monday when she encountered the cow and stopped to let the animal cross.

Instead, the cow knocked the woman over and stepped on her legs.

Taylor says the woman wasn't seriously hurt. Her name was not released.

The cow had left the area by the time rangers arrived, but other people warned fellow bikers and hikers on the trail about the animal.
